Several sites offer all the graph paper you could ever want including several choices for settings such as the type of paper (eg cartesian or polar), paper size and units. Some such as MathBits offer specialist grids such as trigonometric templates.

I have also included sites offering graphic organizers on the list. These could be used for students to see what they can remember about a topic for example or to outline the steps of an algorithm. See Diagrams on Digital Tools for further resources for creating online diagrams such as mind maps (student version of the page here).

Select the image then different parts of the diagram to see what happens!

Do you ever need a way of choosing a random student or perhaps a timer to display on the IWB? There are various free resources available to help!

This random name selector by John Mclear on Primary Technology will randomly select a name from a list you can easily input. Once you have input a list of names you can then save the list as a link. It is possible to remove a name from the list once it has been chosen.

You can save a list of names so have easy access to lists of all your classes by just having the link somewhere easy to access.
